List comments in a product

Comments can be added to and listed as a sub-resource on any resource that supports them. These resources support comments:

• Features
• Epics
• Requirements
• Ideas
• Initiatives
• Goals
• Releases
• Release phases
• To-dos

They can be listed product-wide, or retrieved from anywhere in the system using the root comments resource.

To reply to a comment, specify the parent_comment_id when creating a comment. The parent must be a top-level comment on the same resource; replies to replies are not supported.
